from palm fronds in Brunei and Thailand. Fungal Diversity 11: 119-122.
Goidanichiella fusiforma sp. novo was identified from collections of decaying palm fronds in
tropical rainforests in Brunei and Thailand. The new taxon is described and illustrated, and
compared with similar taxa.
Key words: anamorphic fungi, palm fungi, systematics, taxonomy.
Introduction
We are studying the fungi occurring on tropical palm species and have
described several species new to science (Yanna et al., 1998a,b, 1999; Goh et
al., 1999). Collections of fungi on fronds of palms in tropical rainforests
yielded a new species of Goidanichiella and this taxon is described and
illustrated in this paper.
Taxonomy
Goidanichiellafusiforma K.D. Hyde, Yanna, Pinnoi & E.B.G. lones, sp. novo
(Figs. 1-7)
Etymology: referring to the fusiform conidia.
Mycelium immersa et superficialia. Conidiophora macronemata, mononemata, solitaria,
erecta, recta vel paulo flexuosa, simplicia, laevia, brunnea, 240-300 x 6-9 Ilm, apicem
subhyalina, apicem inflata 8-12 Ilm. Cellulae conidiogenae monoblasticae, determinatae,
discretae, cylindricae, hyalinae vel pallid brunnae, 11-23 x 2-3 Ilm. Conidia acrogena,
aggregata, hyalina, fusiformes, aseptata, laevia, 9-11 x 2.5-3 Ilm.
Colonies scattered, sparse, brown. Mycelium immersed or superficial,
composed of brown, septate, smooth, thin-walled, branched hyphae. Stoma
absent. Setae and hyphopodia absent. Conidiophores macronematous,

mononematous, solitary, erect, branched at the apex forming stipe and head;
stipe straight or flexuous, swollen at the apex, smooth, cylindrical, brown to
dark brown, paler towards the apex, 240-300 x 6-9 Jlm (x = 255 x 8 Jlm,n =
25); apex forming a swollen head, 8-12 Jlm(x = 10Jlm,n =25), bears primary
branches which themselves bear secondary branches arranged penicillately
(Figs. 1, 6). Conidiogenous cells monoblastic, determinate, terminal, discrete,
cylindrical, hyaline to pale brown, borne atthe endsof secondary branches, 11
23 x 2-3 Jlm(x = 12.5 x 2.5 Jlm,n = 25) (Figs. 2-4, 6). Conidia enteroblastic,
aerogenous, solitary, aggregated in slimy heads, hyaline, fusiform, aseptate,
smooth, 9-11 x 2.5-3 Jlm(x = 9.5 x 2.8 Jlm, n = 25) (Figs. 2-5, 7). Conidial
secession schizolytic.

Colonies on PDA very slow growing, attaining a diameter of 4-5 cm in 5

Forest, on submerged dead petiole of Eleiodoxa conferta, 25 Sep. 2001, A. Pinnoi (Herb.
BIOTEC, AOM 0008).
Habit: Saprobic on fronds of Eleiodoxa conferta (petiole), Oncosperma
horridum (rachis) andSalacca affinis (rachis),
Known distribution: SouthEastAsia(Brunei andThailand).
Notes: Goidanichiella was reviewed by Gams et al. (1990) and a single
species G. barronii W. Gams, Steiman & Seigle-Murandi was accepted.
Goidanichiella sphaerospora Matsush. had been invalidly published and the
121
type material lost. Goidanichiella fusiforma is distinct from G. barronii in
producing relatively large, fusiform conidia (9-11 x 2.5-3 !lm).
The specimen from Thailand had larger conidiophores (205-520 !lm
long, 10-17.5 !lm diam.) with a narrower swollen head (5-7.5 !lm) and slightly
shorter conidiogenous cells (9-12 x 2.5-3 !lm) and slightly longer conidia (11
x
14 x 2-3 !lm, = 11.9 x 2.7, n = 25). As the width of the conidia and
conidiogenous cells are similar and the lengths overlap with those of the Brunei
specimens, we are of the opinion that the Thailand specimen does not require
separate species status.
